## CHANGELOG

Occasionally, bugs are discovered in the APIs used to measure metrics, and sometimes in the definitions of the metrics themselves. As a result, changes must sometimes be made, and these changes can show up as improvements or regressions in your internal reports and dashboards.

To help you manage this, all changes to either the implementation or definition of these metrics will be surfaced in this [CHANGELOG](http://bit.ly/chrome-speed-metrics-changelog).

If you have feedback for these metrics, you can provide it in the [web-vitals-feedback Google group](https://groups.google.com/g/web-vitals-feedback).
